Yesterday was a lot colder than today.

It is colder this year than last year.

The climate of Mars is colder than Earth's.

It's getting colder and colder.

It's a lot colder in Boston than it is here.

Arctic air is deeply cold, colder than polar air masses.

It is getting colder and colder day by day.

The coat is also noticeably shorter than in other lynxes, which are typically adapted to colder environments.

During these dark months the air high over the poles becomes much colder than the air over the equator.

It is getting colder and colder morning and evening. The leaves of trees will soon turn red or yellow.

In 2006, scientists using the Submillimeter Array discovered that Pluto's temperature is about , 10 K colder than would otherwise be expected.

The higher we climb, the colder it becomes.

The higher we went, the colder it became.

The lowest temperature recorded in Uranus's tropopause is 49 K, making Uranus the coldest planet in the Solar System, colder than Neptune.

The Mpemba Effect, named after Erasto Mpemba, is the observation that, in some circumstances, warmer water can freeze faster than colder water.

Is it getting hotter or is it getting colder?

If the water is any colder, it takes longer.

The temperature inside the glass can be defined at any point, but it is colder near the ice cube than far away from it.

Because it reflects so much sunlight, the mean surface temperature at noon only reaches 198 C, making it somewhat colder than other Saturnian satellites.

Come with me to the bottom of the world, Antarctica, the highest, driest, windiest, and yes, coldest region on Earth more arid than the Sahara and, in parts, colder than Mars.

Fire related burns are generally more common in colder climates.

As the weather became colder, he went from bad to worse.

The stability of an air mass may be shown using a third letter, either k (air mass colder than the surface below it) or w (air mass warmer than the surface below it).

They are rich in dissolved oxygen, especially in the western and northern parts, which are colder and have more phytoplankton than the eastern and southern areas.

The upper limit of the Glomma valley farms is variable, but typically runs about in Østerdalen, slightly lower than in Gudbrandsdal, which reflects the colder climate.

Some are colder, some are hotter and it's a bell shaped curve.

This is also why it becomes colder at night at higher elevations.

On colder days, they curl up or dig a hole in the snow.

Conductive cooling occurs when the air comes into contact with a colder surface, usually by being blown from one surface to another, for example from a liquid water surface to colder land.

In liquid this occurs because it exchanges heat with colder liquid through direct exchange.

Colder summer temperatures cause the size, abundance, productivity and variety of plants to decrease.

Western coastal areas of Scotland are warmer than the east and inland areas, due to the influence of the Atlantic currents, and the colder surface temperatures of the North Sea.

Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical.

Conditions were significantly colder, but they were also less intense with respect to the ultraviolet regime.

In a warm occlusion, the air mass overtaking the warm front is warmer than the cold air ahead of the warm front and rides over the colder air mass while lifting the warm air.

The downward moving exterior is caused by colder air being displaced at the top of the thermal.

Because water containing heavier isotopes has a higher heat of evaporation, its proportion decreases with colder conditions.

This forest, composed of specimens of the species Araucaria angustifolia , or pine do Paraná, is common in colder areas.

Due to its situation along the North Atlantic, the city is often subjected to sea breezes, especially in the late spring, when water temperatures are still quite cold and temperatures at the coast can be more than colder than a few miles inland, sometimes dropping by that amount near midday.

If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w. For instance, an air mass originating over the desert southwest of the United States in summer may be designated cT .

Nairobi has a cool climate which becomes colder closer to Mount Kenya, which has only one permanently snow capped peak left.

When Ekman transport is occurring away from the coast, surface waters moving away are replaced by deeper, colder, and denser water.

In some instances, these pockets of colder air can descend rapidly, creating a dry microburst which can be extremely hazardous to aviation.

When a temperature difference does exist heat flows spontaneously from the warmer system to the colder system until they are in thermal equilibrium.

And the smoke from all that burning, along with vehicles, power plants, and industry, gets trapped beneath the colder air above the surrounding mountains.
